Description

Technical Field

[0001] The invention relates to the technical field of food drying, and in particular to temperature-controllable anti-sticking drying equipment for dried mango preserves. Background Art

[0002] Mango preserve drying equipment is a professional equipment used for processing mango preserves. It uses specific structures and technologies, such as hot air circulation, turning device, temperature control, etc., to efficiently dry mango preserves, so that the preserves are evenly heated and dried quickly, improving the quality of the preserves and ensuring production efficiency and product quality.

[0003] In the prior art, the dried mango candied fruit drying equipment has the problem that the dried mango candied fruit is easily adhered to the inner wall of the drying equipment during the drying process, which not only affects the circulation of hot air flow and reduces the drying efficiency, but also increases the difficulty and cost of cleaning the equipment. When the dried mango candied fruit adheres to the inner wall, it may also be partially deteriorated due to uneven heating. Summary of the invention

[0004] In view of the shortcomings of the prior art, the technical solution adopted by the present invention to solve the technical problems is: a temperature-controllable anti-sticking drying device for mango preserved fruit, comprising: a base, the base is used to support the overall components of the device, the top of the base is fixedly connected with a feed shell, the outer side of the feed shell is fixedly connected with a drive motor, and the output shaft of the drive motor is fixedly connected with a spiral feed plate; an auxiliary material adding device, the outer side of the auxiliary material adding device is fixedly connected with the outer side of the feed shell, and the auxiliary material adding device is used to add an anti-sticking agent; a mixing device, the center of the mixing device is fixedly connected with the output shaft of the drive motor, and the mixing device is located directly below the auxiliary material adding device; a drying device, the drying device is used to dry the mango preserved fruit, the bottom of the drying device is fixedly connected with the top of the base, and the outer side of the drying device is fixedly connected with the outer side of the feed shell; a turning device, the outer side of the turning device is rotatably connected with the inner side of the drying device, the turning device is used to turn over the preserved fruit in the drying device, add the anti-sticking agent into the auxiliary material adding device, and then start the drive motor, and its output shaft drives the spiral feed plate to rotate in the feed shell. The spiral feeding plate conveys the dried mango preserves to be dried into the drying device by rotating to complete the drying process;

[0005] The drying device comprises a shell, an air guide shell is fixedly connected to the inner side of the shell, an electric heating wire is fixedly connected to the inner side of the air guide shell, a side of the air guide shell close to the shell is fixedly connected to a flow-dividing jet pipe, a temperature sensor is fixedly connected to the outer side of the flow-dividing jet pipe, a discharge pipe is fixedly connected to the center of the air guide shell, a material guide plate is slidably connected to the inner wall of the discharge pipe, a telescopic cylinder is fixedly connected to the outer side of the material guide plate, a transmission rod is fixedly connected to the output end of the driving motor, a spiral stirring blade is fixedly connected to the outer side of the transmission rod, and the temperature sensor can detect and feedback the air flow temperature of the flow-dividing jet pipe, so that the staff can adjust the current of the electric heating wire and control the drying temperature;

[0006] The material turning device includes a rotating drum, a material turning plate is fixedly connected to the inner side of the rotating drum, a rotating rod is rotatably connected to the outer side of the rotating drum, an arc-shaped knocking block is fixedly connected to the outer side of the rotating rod, and torsion springs are fixedly connected to the two sides of the arc-shaped knocking block. When the arc-shaped knocking block knocks on the surface of the rotating drum to generate vibration, the vibration will be transmitted to the dried preserved fruit, destroying the static friction and adhesion formed between the dried preserved fruit and the inner wall of the rotating drum that may cause adhesion.

[0007] Preferably, the bottom of the shell is fixedly connected to the top of the base, the outer side of the shell is fixedly connected to the outer side of the feed shell, the outer side of the diversion jet pipe is fixedly connected to the inner side of the shell, and the end of the telescopic cylinder away from the guide plate is fixedly connected to the bottom of the discharge pipe. When the telescopic cylinder contracts, the guide plate contacts the edge of the spiral stirring blade. At this time, the dried preserved fruits turning in the rotating drum will fall on the surface of the guide plate, and then the spiral stirring blade rotates to transport the dried preserved fruits to the outside of the discharge pipe.

[0008] Preferably, the outer side of the drum is rotatably connected to the inner side of the housing, one end of the torsion spring away from the arc-shaped knocking block is fixedly connected to the outer side of the drum, and a through hole is provided in the wall of the drum, and the airflow blows into the drum through the through hole when ejected, thereby forming an inward airflow. This airflow can form an air cushion layer between the dried preserved fruit and the inner wall of the drum, which can reduce the direct contact and friction between the dried preserved fruit and the inner wall of the drum, thereby preventing the dried preserved fruit from adhering to the inner wall of the drum.

[0009] Preferably, the auxiliary material adding device includes a feeding barrel, a fixing rod is fixedly connected at the center of the feeding barrel, an anti-blocking rod is fixedly connected to the outer wall of the fixing rod, a compression spring is fixedly connected to the inner wall of the feeding barrel, a protrusion is fixedly connected to the bottom end of the compression spring, a sliding sleeve is fixedly connected to the top of the protrusion, a connecting rod is fixedly connected to the top of the sliding sleeve, and a conical block is fixedly connected to the top of the connecting rod. When the rotating roller in the mixing device contacts the protrusion in the auxiliary material adding device, the protrusion is pushed upward. At this time, the compression spring is compressed, and the sliding sleeve moves upward with the protrusion. At this time, the anti-sticking agent can roll down through the gap between the conical block and the connecting rod.

[0010] Preferably, the bottom of the feed barrel is fixedly connected to the outer side of the feed shell, and the side wall of the sliding sleeve is slidably connected to the inner wall of the feed barrel. When the sliding sleeve moves relative to the fixed rod, the anti-blocking rod will come into contact and interact with the accumulated anti-sticking agent. The existence of the anti-blocking rod can destroy the stable accumulation structure that the anti-sticking agent may form, making it loose and restoring fluidity.

[0011] Preferably, the outer side of the conical block is fixedly connected to a limiting block, the outer wall of the limiting block is fixedly connected to a clearing rod, and the inner side of the limiting block is fixedly connected to a ring-shaped support rod. When the conical block moves upward, the clearing rod clears the anti-sticking agent accumulated in the feeding barrel, and can break the possible blockage in time to ensure that the anti-sticking agent can flow out of the feeding barrel continuously and smoothly. The hole that can be opened in the limiting block can also reduce the obstruction of the limiting block to the falling of the anti-sticking block.

[0012] Preferably, the mixing device includes a shaft sleeve, a stirring frame is fixedly connected to the outer side of the shaft sleeve, a spoiler is fixedly connected to the outer side of the stirring frame, and a rotating roller is rotatably connected to the outer side of the stirring frame. When the spoiler rotates, a strong disturbance is generated in the mixture of the dried preserved fruit and the anti-sticking agent. This disturbance enables the dried preserved fruit and the anti-sticking agent to contact each other more fully, breaking up any stratification or local aggregation between the two.

[0013] Preferably, an elastic plate is fixedly connected to the inner side of the stirring frame, and a cleaning block is fixedly connected to the outer side of the elastic plate, and the cleaning block is always in contact with the surface of the rotating roller under the elastic force of the elastic plate.

[0014] Preferably, the outer wall of the cleaning block is slidably connected to the inner side of the stirring frame, the center of the sleeve is fixedly connected to the output shaft of the driving motor, and the outer side of the cleaning block is slidably connected to the outer wall of the rotating roller, and the cleaning block can clean the rotating roller when the rotating roller rotates.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention provides an auxiliary material adding device, and the spiral feed plate and the mixing device are driven by the same drive motor. When the rotation speed of the spiral feed plate increases (i.e., the conveying rate of the dried preserved fruit increases), the speed of the drive motor also increases accordingly. At this time, the contact frequency between the rotating roller and the protrusion increases, so that the frequency of the protrusion pushing up increases, and the feeding barrel opens more frequently. In this way, the amount of anti-sticking agent added can be automatically adjusted according to the conveying amount of the dried preserved fruit, ensuring that each unit of dried preserved fruit can obtain a suitable proportion of anti-sticking agent, avoiding insufficient addition of anti-sticking agent resulting in adhesion of the dried preserved fruit, or excessive addition resulting in waste of resources and adverse effects on subsequent processing.

[0017] 2. The present invention sets a dredging rod, and the limit block can limit the conical block. When the conical block moves upward, the dredging rod dredges the anti-sticking agent accumulated in the feeding barrel, which can break the possible blockage in time, and ensure that the anti-sticking agent can flow out of the feeding barrel continuously and smoothly. The hole opened in the limit block can also reduce the obstruction of the limit block to the falling of the anti-sticking block. By setting an annular support rod to provide auxiliary support for the limit block, thereby increasing its structural strength, the limit block can be prevented from shifting during movement.

[0018] 3. The present invention provides an anti-blocking rod. During the anti-sticking agent delivery process, the anti-sticking agent may accumulate inside or around the sliding sleeve. When the sliding sleeve moves relative to the fixed rod, the anti-blocking rod will come into contact with and interact with the accumulated anti-sticking agent. The existence of the anti-blocking rod can destroy the stable accumulation structure that the anti-sticking agent may form, making it loose and restoring fluidity, so that the anti-sticking agent accumulated in the sliding sleeve can flow downward smoothly under the relative action of the anti-blocking rod.

[0019] 4. The present invention provides a mixing device, and the output shaft of the driving motor drives the stirring frame to rotate through the shaft sleeve. At this time, the spoiler rotates together with the stirring frame. When the spoiler rotates, it will generate strong disturbance in the mixture of the dried preserved fruit and the anti-sticking agent. This disturbance enables the dried preserved fruit and the anti-sticking agent to contact each other more fully, breaking the possible stratification or local aggregation between the two. Preliminary mixing is performed before entering the drying device, which allows the anti-sticking agent to adhere to the surface of the dried preserved fruit more evenly, ensuring that each piece of dried preserved fruit can be effectively anti-sticked.

[0020] 5. The present invention provides a mixing device so that the cleaning block is always in contact with the surface of the rotating roller under the elastic force of the elastic plate, thereby cleaning the rotating roller when the rotating roller rotates, preventing agglomerations of the anti-sticking agent or other impurities from adhering to the surface of the rotating roller.

[0021] 6. The present invention provides a turning device, and the dried preserved fruits fall into the rotating drum under the action of gravity. At this time, the output shaft of the driving motor drives the rotating drum to rotate in the outer shell through the transmission rod. At this time, the dried preserved fruits can be continuously turned in the rotating drum under the obstruction of the turning plate. Therefore, during the drying process, through the continuous turning of the turning plate, each piece of dried preserved fruit can be continuously changed in position and evenly exposed to the hot air flow, ensuring that the heat and drying degree they receive are consistent, avoiding local overheating or insufficient drying, thereby improving the overall drying quality.

[0022] 7. The present invention provides a drying device, and the temperature sensor can detect and feedback the airflow temperature of the split jet pipe, so that the staff can adjust the current of the electric heating wire and then control the drying temperature. At this time, the hot air ejected can dry the dried preserved fruit, and the airflow blows into the drum through the through hole when ejected, thereby forming an inward airflow. This airflow can form an air cushion layer between the dried preserved fruit and the inner wall of the drum, which can reduce the direct contact and friction between the dried preserved fruit and the inner wall of the drum, thereby preventing the dried preserved fruit from adhering to the inner wall of the drum.

[0023] 8. The present invention provides an arc-shaped knocking block. When the arc-shaped knocking block knocks the surface of the drum to generate vibration, the vibration will be transmitted to the dried fruit, destroying the static friction and adhesion between the dried fruit and the inner wall of the drum that may cause adhesion. The vibration causes the contact state between the dried fruit and the inner wall of the drum to change continuously, making it difficult to form a stable adhesion condition, thereby effectively preventing the dried fruit from adhering to the inner wall of the drum.

[0024] 9. The present invention sets a material guide plate, and the telescopic cylinder contracts and drives the material guide plate to slide along the inner wall of the discharge pipe. At this time, one end of the material guide plate is inside the inner and outer shell of the machine and contacts the edge of the spiral stirring blade. At this time, the dried preserved fruits turning in the rotating drum will fall on the surface of the material guide plate. Then, the transmission rod drives the spiral stirring blade to rotate and transports the dried preserved fruits to the outside of the discharge pipe, completing the discharge process and improving the smoothness of the discharge.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0036] Example: See Figure 1 - Fig. 9 The present invention provides a technical solution: a temperature-controllable anti-sticking drying device for dried mango preserves, comprising:

[0037] A base 1 is used to support the overall components of the equipment. A feed shell 2 is fixedly connected to the top of the base 1. A drive motor 7 is fixedly connected to the outside of the feed shell 2. A spiral feed plate 4 is fixedly connected to the output shaft of the drive motor 7; an auxiliary material adding device 5. The outside of the auxiliary material adding device 5 is fixedly connected to the outside of the feed shell 2. The auxiliary material adding device 5 is used to add an anti-sticking agent; a mixing device 6. The center of the mixing device 6 is fixedly connected to the output shaft of the drive motor 7. The mixing device 6 is located directly below the auxiliary material adding device 5; a drying device 3. The drying device 3 is used to dry the dried mango preserves. The bottom of the drying device 3 is fixedly connected to the top of the base 1, and the outer side of the drying device 3 is fixedly connected to the outer side of the feed shell 2. The turning device 8 is rotatably connected to the inner side of the drying device 3. The turning device 8 is used to turn the dried mango preserves in the drying device 3, and the dried mango preserves are put into the top of the feed shell 2 installed on the outer side of the base 1. Then, the anti-sticking agent is added to the auxiliary material adding device 5, and then the driving motor 7 is started, and its output shaft drives the spiral feed plate 4 to rotate in the feed shell 2. The spiral feed plate 4 transports the dried mango preserves to be dried into the drying device 3 by rotation, completing the drying process;

[0038] The drying device 3 includes a shell 31, an air guide shell 32 is fixedly connected to the inner side of the shell 31, an electric heating wire 38 is fixedly connected to the inner side of the air guide shell 32, a split jet pipe 39 is fixedly connected to the side of the air guide shell 32 close to the shell 31, a temperature sensor 30 is fixedly connected to the outer side of the split jet pipe 39, a discharge pipe 33 is fixedly connected to the center of the air guide shell 32, a guide plate 34 is slidably connected to the inner wall of the discharge pipe 33, a telescopic cylinder 35 is fixedly connected to the outer side of the guide plate 34, a transmission rod 36 is fixedly connected to the output end of the drive motor 7, a spiral stirring blade 37 is fixedly connected to the outer side of the transmission rod 36, and the turning device 8 includes a rotating drum 81, the inner side of the rotating drum 81 is fixedly connected with a turning plate 82, the outer side of the rotating drum 81 is rotatably connected with a rotating rod 84, the outer side of the rotating rod 84 is fixedly connected with an arc-shaped knocking block 85, and the two sides of the arc-shaped knocking block 85 are fixedly connected with torsion springs 86, the bottom of the shell 31 is fixedly connected to the top of the base 1, the outer side of the shell 31 is fixedly connected to the outer side of the feed shell 2, the outer side of the diversion jet pipe 39 is fixedly connected to the inner side of the shell 31, the end of the telescopic cylinder 35 away from the guide plate 34 is fixedly connected to the bottom of the discharge pipe 33, the outer side of the rotating drum 81 is rotatably connected to the inner side of the shell 31, and the torsion spring 86 is away from the arc-shaped knocking block 85. One end is fixedly connected to the outer side of the rotating drum 81, and a through hole 83 is opened in the wall of the rotating drum 81. When the mixed dried preserved fruits enter the drying device 3, the dried preserved fruits fall into the rotating drum 81 in the turning device 8 under the action of gravity. At this time, the output shaft of the driving motor 7 drives the rotating drum 81 to rotate in the outer shell 31 through the transmission rod 36. At this time, the dried preserved fruits can be continuously turned in the rotating drum 81 under the obstruction of the turning plate 82. Therefore, during the drying process, through the continuous turning of the turning plate 82, each piece of dried preserved fruits can continuously change its position and be evenly exposed to the hot air flow, ensuring that the heat they receive and the degree of drying are consistent. , avoiding local overheating or insufficient drying, thereby improving the overall drying quality; in this process, an air pump is connected to the outside of the air inlet of the air guide shell 32, and then the heating wire 38 is energized. At this time, the air flow enters the air guide shell 32 to form a hot air flow, and is ejected outward through the split jet pipe 39, wherein the temperature sensor 30 can detect and feedback the air flow temperature of the split jet pipe 39, so that the staff can adjust the current size of the heating wire 38, and then control the drying temperature. At this time, the ejected hot air can dry the dried preserved fruit, and the air flow blows into the rotating drum 81 through the through hole 83 when ejected, thereby forming an inward air flow.This airflow can form an air cushion layer between the dried preserved fruit and the inner wall of the rotating drum 81, which can reduce the direct contact and friction between the dried preserved fruit and the inner wall of the rotating drum 81, thereby preventing the dried preserved fruit from adhering to the inner wall of the rotating drum 81. It can also prevent the dried preserved fruit from adhering to the inner wall of the rotating drum 81; in this process, when the blown airflow blows on the surface of the arc-shaped knocking block 85, the arc-shaped knocking block 85 will drive the rotating rod 84 to deflect under the thrust of the airflow, and the torsion spring 86 is twisted under the force at this time, and then the arc-shaped knocking block 85 knocks on the surface of the rotating drum 81; when the arc-shaped knocking block 85 knocks on the surface of the rotating drum 81 to generate vibration, this vibration will be transmitted to the dried preserved fruit, destroying the static friction and adhesion formed between the dried preserved fruit and the inner wall of the rotating drum 81 that may cause adhesion. The vibration causes the contact state between the dried preserved fruit and the inner wall of the rotating drum 81 to change continuously, making it difficult to form stable attachment conditions, thereby effectively preventing the dried preserved fruit from adhering to the inner wall of the rotating drum 81. When discharging, the telescopic cylinder 35 contracts and drives the guide plate 34 to slide along the inner wall of the discharge pipe 33. At this time, one end of the guide plate 34 is inside the inner shell 31 of the machine and contacts the edge of the spiral stirring blade 37. At this time, the dried preserved fruit turning in the rotating drum 81 will fall on the surface of the guide plate 34, and then the transmission rod 36 drives the spiral stirring blade 37 to rotate and transport the dried preserved fruit to the outside of the discharge pipe 33, completing the discharging process and improving the smoothness of the discharging.

[0039] The auxiliary material adding device 5 includes a feeding barrel 51, a fixing rod 52 is fixedly connected at the center of the feeding barrel 51, an anti-blocking rod 53 is fixedly connected to the outer wall of the fixing rod 52, a compression spring 55 is fixedly connected to the inner wall of the feeding barrel 51, a convex block 54 is fixedly connected to the bottom end of the compression spring 55, a sliding sleeve 56 is fixedly connected to the top of the convex block 54, a connecting rod 57 is fixedly connected to the top of the sliding sleeve 56, a conical block 58 is fixedly connected to the top of the connecting rod 57, the bottom of the feeding barrel 51 is fixedly connected to the outer side of the feed shell 2, the side wall of the sliding sleeve 56 is slidably connected to the inner wall of the feeding barrel 51, the outer side of the conical block 58 is fixedly connected to the limiting block 50, the outer wall of the limiting block 50 is fixedly connected to the dredging rod 510, the inner side of the limiting block 50 The spiral feed plate 4 is fixedly connected with a ring support rod 59. When the drive motor 7 is working, the spiral feed plate 4 conveys the dried fruit by rotating. At the same time, the output shaft of the drive motor 7 also drives the mixing device 6 to rotate. When the rotating roller 64 in the mixing device 6 contacts the protrusion 54 in the auxiliary material adding device 5, the protrusion 54 is pushed upward. At this time, the compression spring 55 is compressed, and the sliding sleeve 56 moves upward with the protrusion 54. At this time, the anti-adhesive agent can roll down through the gap between the conical block 58 and the connecting rod 57; because the spiral feed plate 4 and the mixing device 6 are driven by the same drive motor 7, when the rotation speed of the spiral feed plate 4 is accelerated (that is, the conveying rate of the dried fruit is increased), the speed of the drive motor 7 is also increased accordingly. At this time, the contact frequency between the rotating roller 64 and the protrusion 54 increases, so that the frequency of the protrusion 54 pushing upward is accelerated, and the feeding barrel 51 is opened more frequently. In this way, the amount of anti-sticking agent added can be automatically adjusted according to the conveying amount of dried preserved fruits, ensuring that each unit of dried preserved fruits can obtain an appropriate proportion of anti-sticking agent, avoiding insufficient addition of anti-sticking agent that causes the dried preserved fruits to stick together, or excessive addition that causes waste of resources and adverse effects on subsequent processing. In this process, the limit block 50 can limit the conical block 58, and the dredging rod 510 can dredge the anti-sticking agent accumulated in the feeding barrel 51 as the conical block 58 moves upward, and can break the possible blockage in time to ensure that the anti-sticking agent can flow out of the feeding barrel 51 continuously and smoothly. The hole that can be opened in the limit block 50 can also reduce the obstruction of the limit block 50 when the anti-sticking block falls. By setting the annular strut 59 to provide auxiliary support for the limit block 50, thereby increasing its structural strength, the limit block 50 can be prevented from shifting during movement; during the anti-sticking agent transportation process, the anti-sticking agent may accumulate inside or around the sliding sleeve 56. When the sliding sleeve 56 moves relative to the fixed rod 52, the anti-blocking rod 53 will come into contact with and interact with the accumulated anti-sticking agent. The existence of the anti-blocking rod 53 can destroy the stable accumulation structure that the anti-sticking agent may form, making it loose and restoring fluidity, so that the anti-sticking agent accumulated in the sliding sleeve 56 can flow downward smoothly under the relative action of the anti-blocking rod 53.

[0040] The mixing device 6 includes a shaft sleeve 61, the outer side of the shaft sleeve 61 is fixedly connected to a stirring frame 62, the outer side of the stirring frame 62 is fixedly connected to a spoiler 63, the outer side of the stirring frame 62 is rotatably connected to a rotating roller 64, the inner side of the stirring frame 62 is fixedly connected to an elastic plate 65, the outer side of the elastic plate 65 is fixedly connected to a cleaning block 66, the outer wall of the cleaning block 66 is slidably connected to the inner side of the stirring frame 62, the center of the shaft sleeve 61 is fixedly connected to the output shaft of the driving motor 7, the outer side of the cleaning block 66 is slidably connected to the outer wall of the rotating roller 64, when the mixing device 6 is in use, the output shaft of the driving motor 7 drives the stirring frame 62 to rotate through the shaft sleeve 61, and at this time the spoiler 63 rotates with the stirring frame The spoiler 63 rotates together with the dried preserved fruit and the anti-sticking agent, and this disturbance enables the dried preserved fruit and the anti-sticking agent to contact each other more fully, breaking the stratification or local aggregation that may exist between the two. The preliminary mixing before entering the drying device 3 can make the anti-sticking agent adhere to the surface of the dried preserved fruit more evenly, ensuring that each piece of dried preserved fruit can be effectively anti-sticked. During this process, the cleaning block 66 is always in contact with the surface of the rotating roller 64 under the elastic force of the elastic plate 65, so that the rotating roller 64 can be cleaned when the rotating roller 64 rotates, preventing the anti-sticking agent from agglomerating or other impurities from adhering to the surface of the rotating roller 64.

[0041] Working principle:

[0042] The dried mangoes are placed from the top of the feed shell 2 installed outside the base 1, and then the anti-sticking agent is added into the auxiliary material adding device 5, and then the driving motor 7 is started, and its output shaft drives the spiral feed plate 4 to rotate in the feed shell 2. The spiral feed plate 4 rotates to transport the dried mangoes to be dried into the drying device 3, completing the drying process;

[0043] When the driving motor 7 is working, the spiral feeding plate 4 conveys the dried preserved fruit by rotating. At the same time, the output shaft of the driving motor 7 also drives the mixing device 6 to rotate. When the rotating roller 64 in the mixing device 6 contacts the protrusion 54 in the auxiliary material adding device 5, the protrusion 54 is pushed upward. At this time, the compression spring 55 is compressed, and the sliding sleeve 56 moves upward with the protrusion 54. At this time, the anti-sticking agent can roll down through the gap between the conical block 58 and the connecting rod 57;

[0044] Since the spiral feed plate 4 and the mixing device 6 are driven by the same drive motor 7, when the rotation speed of the spiral feed plate 4 is increased (i.e., the conveying rate of the dried fruit is increased), the rotation speed of the drive motor 7 is also increased accordingly. At this time, the contact frequency between the rotating roller 64 and the protrusion 54 increases, so that the frequency of the protrusion 54 pushing up is increased, and the feeding barrel 51 is opened more frequently. In this way, the amount of anti-sticking agent added can be automatically adjusted according to the conveying amount of the dried fruit, ensuring that each unit of dried fruit can get the anti-sticking agent in a suitable proportion, avoiding insufficient addition of anti-sticking agent to cause the dried fruit to stick together, or excessive addition to cause waste of resources and adverse effects on subsequent processing.

[0045] During this process, the limit block 50 can limit the conical block 58, and the dredging rod 510 can dredge the anti-sticking agent accumulated in the feeding tube 51 as the conical block 58 moves upward, so as to break the possible blockage in time and ensure that the anti-sticking agent can continuously and smoothly flow out of the feeding tube 51. The hole that can be opened in the limit block 50 can also reduce the obstruction of the limit block 50 to the anti-sticking block when it falls. By setting the annular support rod 59 to provide auxiliary support for the limit block 50, the structural strength thereof can be increased, and the limit block 50 can be prevented from deflecting during movement.

[0046] During the process of conveying the anti-adhesive agent, the anti-adhesive agent may accumulate inside or around the sliding sleeve 56. When the sliding sleeve 56 moves relative to the fixed rod 52, the anti-blocking rod 53 will come into contact with and interact with the accumulated anti-adhesive agent. The existence of the anti-blocking rod 53 can destroy the stable accumulation structure that the anti-adhesive agent may form, making it loose and restoring fluidity, so that the anti-adhesive agent accumulated in the sliding sleeve 56 can flow downward smoothly under the relative action of the anti-blocking rod 53.

[0047] When the mixing device 6 is in use, the output shaft of the driving motor 7 drives the stirring frame 62 to rotate through the shaft sleeve 61. At this time, the spoiler 63 rotates together with the stirring frame 62. The spoiler 63 will generate strong disturbance in the mixture of dried preserved fruit and anti-sticking agent when rotating. This disturbance enables the dried preserved fruit and the anti-sticking agent to contact each other more fully, breaking the possible stratification or local aggregation between the two. Preliminary mixing before entering the drying device 3 can allow the anti-sticking agent to adhere to the surface of the dried preserved fruit more evenly, ensuring that each piece of dried preserved fruit can be effectively anti-sticked.

[0048] During this process, the cleaning block 66 is always in contact with the surface of the rotating roller 64 under the elastic force of the elastic plate 65, so that the rotating roller 64 can be cleaned when the rotating roller 64 rotates to prevent the anti-sticking agent from agglomerating or other impurities from adhering to the surface of the rotating roller 64;

[0049] After the mixed dried fruits enter the drying device 3, the dried fruits fall into the rotating drum 81 in the turning device 8 under the action of gravity. At this time, the output shaft of the driving motor 7 drives the rotating drum 81 to rotate in the housing 31 through the transmission rod 36. At this time, the dried fruits can be continuously turned in the rotating drum 81 under the obstruction of the turning plate 82. Therefore, during the drying process, each piece of dried fruits can be continuously changed in position through the continuous turning of the turning plate 82, and evenly exposed to the hot air flow, ensuring that the heat and drying degree they receive are consistent, avoiding local overheating or insufficient drying, thereby improving the overall drying quality;

[0050] In this process, an air pump is connected to the outside of the air inlet of the air guide shell 32, and then the electric heating wire 38 is energized. At this time, the airflow enters the air guide shell 32 to form a hot airflow, and is ejected outward through the split jet pipe 39. Among them, the temperature sensor 30 can detect and feedback the airflow temperature of the split jet pipe 39, so that the staff can adjust the current of the electric heating wire 38, and then control the drying temperature. At this time, the ejected hot air can dry the dried preserved fruits. When the airflow is ejected, it blows into the rotating drum 81 through the through hole 83, thereby forming an inward airflow. This airflow can form an air cushion layer between the dried preserved fruits and the inner wall of the rotating drum 81, which can reduce the direct contact and friction between the dried preserved fruits and the inner wall of the rotating drum 81, thereby preventing the dried preserved fruits from adhering to the inner wall of the rotating drum 81. It can also prevent the dried preserved fruits from adhering to the inner wall of the rotating drum 81;

[0051] During this process, when the blown airflow hits the surface of the arc-shaped knocking block 85, the arc-shaped knocking block 85 will drive the rotating rod 84 to deflect under the thrust of the airflow, and the torsion spring 86 is twisted under force, and then the arc-shaped knocking block 85 knocks on the surface of the rotating drum 81;

[0052] When the arc-shaped knocking block 85 knocks the surface of the rotating drum 81 to generate vibration, the vibration will be transmitted to the dried preserved fruit, destroying the static friction and adhesion between the dried preserved fruit and the inner wall of the rotating drum 81 that may cause adhesion. The vibration causes the contact state between the dried preserved fruit and the inner wall of the rotating drum 81 to change continuously, making it difficult to form a stable adhesion condition, thereby effectively preventing the dried preserved fruit from adhering to the inner wall of the rotating drum 81.

[0053] When discharging, the telescopic cylinder 35 contracts and drives the guide plate 34 to slide along the inner wall of the discharge pipe 33. At this time, one end of the guide plate 34 is inside the inner shell 31 of the machine and contacts the edge of the spiral stirring blade 37. At this time, the dried preserved fruits turning in the rotating drum 81 will fall on the surface of the guide plate 34. Then, the transmission rod 36 drives the spiral stirring blade 37 to rotate and transport the dried preserved fruits to the outside of the discharge pipe 33, completing the discharging process and improving the smoothness of the discharging.
